PRIOR TO OPERATION:
1. POWER SOURCE: Ensure that the power source to be utilized conforms to the power specications
on the nameplate.
2. GROUNDING: This tool should be grounded while in use to protect the operator from electric shock.
This tool is equipped with a three conductor cord and grounding type plug to t the proper grounding
receptacle. The green (or green and yellow) conductor in the cord is the grounding wire. Never connect
the green (or green and yellow) wire to a live terminal.
3. POWER SWITCH: Make sure the power switch is in the OFF position. If the plug is connected to a
power receptacle while the power switch is in the ON position. Make sure you are ready to start work
before starting the tool. Failure to do so may cause serious injury.
4. EXTENSION CORD: ALWAYS use an extension cord of sufcient thickness and rated capacity. The
extension cord should be kept as short as is practical.
5. FEEDING OIL: Prior to using the power tool. Remove the oil gauge and ll the oil tank with the provided
oil. Although the oil tank is built in, it contains only a small amount of oil when shipped from the factory.
MOUNTING A TOOL:
(A) Rotate the Stop Lever 180-degrees in a clockwise
direction while pulling it towards you. Next, insert the
tool shank into the hexagonal hole on the front cover.
(B) Clamp the tool by turning the stop lever half a turn in the
opposite direction. NOTE: When removing the tool, follow the
above procedure in reverse order.
COMMON APPLICATIONS:
USING THE HAMMER: After placing the tip of the tool in the
base, hold the switch ON. By utilizing the weight of the machine
and rmly holding the hammer with both hands, one can
effectively control the recoil motion. Proceed at a moderate work
rate. The use off too much force will impair efciency.
CAUTION: Sometimes the tool will not begin the striking stroke even when the motor rotates because the
oil has become too thick. If the tool is used at low temperatures, or if it is used after an extended idle time,
the tool should be used after running it for ve minutes to warm it up.

MAINTENANCE AND INSPECTION
OIL FEEDING: Prior to oil feeding, ALWAYS disconnect the
plug from the power receptacle. Since the oil chamber is built
into the tool, it can be used approximately 20 days at 3-4 hours
a day, without supplying lubricating oil.
Just before there is no oil visible in the oil gauge window when
holding the hammer upright use the provided wrench to remove
the oil gauge. Be careful not to lose the rubber backing attached
below the oil gauge. Fill the chamber with oil.
Check the oil level daily, conrming the oil level is full. After
feeding oil be sure to securely clamp the oil gauge.
INSPECTING THE TOOL: Using a dull or worn tool can cause
motor malfunctions and degraded efciency. Replace with a new tool
when wear is noted.
Inspecting the Mounting Screws: Regularly inspect all mounting
screws and ensure they are sufciently tightened. Should any of the
screws be loose. Re-tighten immediately before use.
Maintenance of the Motor: The motor unit Winding is essential to
the power tool. Ensure the Winding does not become damaged or wet
with oil or water.
Inspecting the Carbon Brushes: The motor employs carbon brushes which
are consumable parts. When they become worn, or near to wear limit, it can
result in motor malfunction when the “Auto-Stop” carbon brush is equipped,
the motor will stop automatically. At that time, replace both carbon brushes
with new ones. Always keep brushes clean and ensure they slide freely within
the brush holders. The carbon brush can be removed by removing the cap
cover. Cap rubber and brush cap in the order at the interior.
NOTE: Due to continuing program research and development, the specications herein are subject to
change without prior notice.
Lubrication: Your tool comes has been properly lubricated and ready for use. It is recommended that tools
with gears be re-greased with a gear lubricant at every brush change.
Bearings: Every second brush change, the bearings should be replaced by a qualied technician.
Bearings that become noisy, due to heavy load or very abrasive material cutting, should be replaced
immediately to avoid overheating or motor failure.
Cleaning: Disconnect the tool from power source prior to maintenance or cleaning of the power tool. The
tool may be cleaned most effectively with compressed dry air. Ventilation openings and switch levers must
be kept clean and free of foreign matter. Do not attempt to clean by inserting pointed objects through
openings.
Certain cleaning agents and solvents damage plastic parts. Some of these are gasoline, carbon tetrachloride,
chlorinated cleaning solvents, ammonia and household detergents that contain ammonia.
